Refer to Figure 4.2.
1. With the valve in the full closed position, remove Stop Screw Cover (piece #16).
2. Remove the Lock Screw (piece #17).
3. Adjust the appropriate Stop Screw (piece #17) based on rotation of the drive sleeve — inward if valve is closed
and stop has not yet been reached, or outward if stop has been reached and valve is not yet fully closed.
4. Once the Stop Screw is set, lock securely with Lock Screw.
5. Operate the valve to fully open position and set open stop in the same manner.
